当将以太发送到合同地址时，它将在您的合同中调用此函数：

function () payable whenNotPaused beforeDeadline afterStartTime saleNotClosed  {
    require(msg.value >= minContribution);

    // Update the sender's balance of wei contributed and the amount raised
    uint amount = msg.value;
    uint currentBalance = balanceOf[msg.sender];
    balanceOf[msg.sender] = currentBalance.add(amount);
    amountRaised = amountRaised.add(amount);

    // Compute the number of tokens to be rewarded to the sender
    // Note: it's important for this calculation that both wei
    // and PDT have the same number of decimal places (18)
    uint numTokens = amount.mul(rate);

    // Transfer the tokens from the crowdsale supply to the sender
    if (tokenReward.transferFrom(tokenReward.owner(), msg.sender, numTokens)) {
        FundTransfer(msg.sender, amount, true);
        // Check if the funding goal or cap have been reached
        // TODO check impact on gas cost
        checkFundingGoal();
        checkFundingCap();
    }
    else {
        revert();
    }
}

如果下列任何一种方式之一，交易将被恢复：

• 合同暂停
• 最后期限后
• 开始前时间
• 出售已结束
• 价值小于最低贡献。
• 已达到供资目标或上限
